Ascorbic acid, also referred to as vitamin C(Vc), is an important nutrient found in fruits and vegetables that promotes produce quality and human health. Rosa roxburghii is an underutilized natural fruit that contains very high levels of Vc. however, the Vc content of R. roxburghii varies considerably during plant development and ripening. To better understand the molecular mechanisms that underlie fluctuations in Vc content of R. roxburghii fruit at different developmental stages, we performed transcriptomic and metabolomic analyses and identified two significant gene networks/modules and 168 transcription factors directly involved in Vc synthesis. Promoter analysis of two core genes involved in Vc synthesis, RrGGP and RrGalUR, revealed the presence of a retroviral long terminal repeat(LTR) insert in the RrGalUR promoter. Using yeast one-hybrid and dual-luciferase assays, we demonstrated that the transcription factors RrhY5h and RrZIP9 bind to the promoter of RrGGP to promote its expression. RrZIP6 and RrWRKY4 bind to the LTR in the RrGalUR promoter to promote its expression. Our results reveal a molecular mechanism that controls Vc synthesis and accumulation in R. roxburghii fruit.
